Hi All
I am using S25F256L flash chip and connected to STM32F7 microcontroller.
Accidently the SRP1 and SRP1_D bits are set, but at the same time SRP0 (SR1V[7]) is not set.
So is there any way i can reset it back to factory defaults?
Will the WP# or hardware reset RESET# can help to revert back to factory defaults?
Looking out for suggestions?
Regards
Jufail

Hi Jufail,
Please see the description for SRP1_D bit in the S25FL256L datasheet -
The bit type is OTP, means one time programmable. This bit can be programmed only once (and while IRP[2:0] bit are '111') to change its default state from 0 to 1. Unfortunately, it cannot be changed back to 0.
Does this answer your question?
Regards.
